Stuck on an issue?

Lightrun Answers was designed to reduce the constant googling that comes with debugging 3rd party libraries. It collects links to all the places you might be looking at while hunting down a tough bug.

And, if you’re still stuck at the end, we’re happy to hop on a call to see how we can help out.

The default settings result in too many tiles (2x4).

See original GitHub issue

The file size increased and I tested the number of tiles. (Andvanced settings good 1x1 tiles.) Win 7 x64, ver.:1.2, Encoder: aomenc. CLI (The value at the end of the lines.) :

The tiles in AV1 are in log2, this means:

1 -> 2 2 -> 4 3 -> 8 4 -> 16

If you still think that there is an issue, please provide the program.log file (disable “Delete Temp Files after Encode” inorder to prevent it get deleted).

Many Greetings
